Hi,

first of all, I'm fairly new to ASP.NET as well as developing with IG components, so this may be a quite simple question for experienced users I guess.

I'm using several dropdownproviders in my webdatagrid. Every is working well, until it comes to the first postback after the initial one. I'm creating the data for the dropdown by creating a DataTable and filling it manually like this:

dr = dt.NewRow()

dr("text") = "-"

dr("value") = "L"

dt.Rows.Add(dr)

The Problem is: after the initial loading, everything is fine. The dropdown displays "-" to the user and the value is set to "L". 

BUT: after the next postback, the grid changes the content of the dropdown visible to the user to the value, in this case it displays "L" instead of the desired "-".

The code for the grid is this:

<ig:WebDataGrid ID="grdTest" runat="server" AutoGenerateColumns="false" EnableAjax="false" EnableViewState="true" EnableDataViewState="true" ShowFooter="true" StyleSetName="Office2007Blue" Width="100%" DataKeyFields="rownumber,anr"> 

Any help would be greatly appreciated.

Thanks in advance,

Matthias
